如清单3所示，它不仅删除函数，还消除了调用者管理subprocess_info结构的必要性。
As shown in Listing 3, this not only removes a function but also removes the need for the caller to manage the subprocess_info structure.
由于高阶函数的可用性，确定数字是否完全的整个问题在Groovy中只需几行代码即可完成，如清单7所示。
With the availability of higher-order functions, the entire problem of determining if a number is perfect or not collapses to a couple of lines of code in Groovy, as shown in Listing 7.
